Is Idina Menzel going back to Glee?

Rumor has it that Idina Menzel -- aka the Broadway superstar from the famed "Wicked!" -- will be heading back to "Glee" next fall, marking the most recent in a series of changes to the Glee cast for Season 3. 

Menzel, who has appeared on the show in the past as Rachel Berry's biological mom, is said to be taking on an additional role this time around: as a teacher at William McKinley High School. Does this mean competition for Mr. Shue? I guess we'll have to wait and see. In the meantime, what do you think about Menzel's return to the show? Were you a fan the first time around?
